Election Day 2016 marks the end of a golden era for late-night comedians, as the Donald Trump campaign, in all its name-mangling, endorsement-embellishing, bad-tweeting, big-league glory, is finally coming to an end. And although the likes of Samantha Bee and Trevor Noah have done a lovely job supplying levity over the past year, this has been a particularly difficult election to weather with neither Jon Stewart's Daily Show nor Stephen Colbert's Colbert Report. Thankfully, since one of those two gentlemen is still on TV, the old friends were able to reunite on Colbert's The Late Show for one last get-out-the-vote musical PSA.

It started ordinarily enough, with a charming musical debate between Colbert and a jaded young girl over whether voting really matters. And just then, when Colbert wrapped up the bit and began introducing the announced guests, this happened:

The top-hatted, white-sashed Stewart scoffed haughtily at Colbert, arguing that democracy is optional and encouraging the little girl to eat a toffee—of course he supplied toffee—instead of voting. An alarmed Colbert quickly pulled Stewart aside and asked if he knew who was actually running. But before Colbert could share, a barely-holding-it-together Stewart filled up a water cup and took a looooong sip. You can see the joke coming the whole way, and it's still funny. (It's also funny when the immediately incensed Stewart, claiming to be "still a bit parched," asks Colbert to repeat himself.)
